Figure 4. IL-5, IL-20, and IL-28A induced wound healing migration of bladder cancer 253J and EJ cells.

(A, B) The confluent bladder cancer cells were incubated with serum free medium and treated with recombinant protein IL-5, IL-20, and IL-28A for the indicated times. The widths of injury lines made in cells were then examined at 0 and 24 h. Wound-healing migration is represented by the widths of injury lines.
